Corruption of batch.js under Firefox 59

[voxvalue]

Hi All

Our JIRA Enterprise site runs correctly until the arrival of Firefox 59. Now, we encounter the following error :

An exception has occurred in https://..../s/75a8961202c641df2191b55d2e6cf41b-CDN/rrp4xz/77002/b6b48b2829824b869586ac216d119363/10c7275e79da154a57411f7bb8899739/_/download/contextbatch/js/greenhopper-rapid-non-gadget,atl.general,gh-rapid,jira.project.sidebar,com.atlassian.jira.projects.sidebar.init,jira.global,jira.general,-_super/batch.js?agile_global_admin_condition=true&is-server-instance=true&is-system-admin=true&jag=true&jaguser=true&jira-nps-enabled=true&locale=en-US&nps-acknowledged=true&nps-not-opted-out=true&richediton=true at 8060:0 --- NS_ERROR_FILE_CORRUPTED:

All errors concern the file batch.js.

Our site runs correctly under Chrome 64.

Thanks in advance
